Didn’t expect to use Lua for embedded dev,now I’m using it on microcontrollers

I always thought Lua was just for game noscripting or tweaking config files, didn’t even know people were using it to control hardware. Recently tried it out on an esp32 (was just playing around with IoT stuff) and was surprised how smooth it felt. I wrote Lua code in the browser, pushed it straight to the device, and got a working UI with MQTT + TLS in way less time than it would’ve taken me in c.

Didn’t need any local installs, toolchains, or compiling, just write + run.

Kinda wild that something this lightweight is doing so much. Curious if anyone else here using Lua in embedded or low-resource environments? Would love to see what tools/setups you’re using.

Lua Test and Automation Framework (TAF)

I am an Embedded Firmware Engineer and a few months ago my friend showed me a Robot Framework his company uses for writing end-to-end tests for the embedded devices.
I was speechless. Let's just say that I did not like it :)

So I decided to write a single tool that could:

run fast unit-style tests and longer integration tests,
talk to embedded boards over serial and drive browsers with WebDriver,
print pretty TUI dashboards in the terminal without heavyweight IDEs,
let me noscript everything in a high-level language but still drop to C when I need raw speed or OS access.

so I kindly present TAF (Test-Automation Framework).

---

### Feature list

| Feature | TL;DR |
|---------|-------|
| Lua 5.4 test files | Dead-simple taf.test("name", function() … end) syntax; hot reload; no DSL to learn. |
| C core | The harness itself is a ~7 K LOC C binary → instant startup, tiny footprint. |
| Serial module | Enumerate ports, open/close, read_until() helper with timeouts/patterns – perfect for embedded bring-up logs. |
| Web module | Thin WebDriver wrapper (POST/GET/DELETE/PUT) → drive Chrome/Firefox/Safari from the same Lua tests. |
| Process module | Spawn external procs (taf.proc.spawn()), capture stdin/stdout/stderr, kill & wait – good for CLI apps. |
| TUI dashboard | ncurses fallback (or Notcurses if available) – live view of “current test, current file:line, last log entry, pass/fail counter”. |
| Defer hooks | taf.defer(fn, …) to guarantee cleanup even if an assert() explodes. |
| Pluggable logs | Structured JSON log file + pretty colourised console output -> pipe into Grafana or just cat. |

### Quick taste (Serial)

local taf = require("taf")
local serial = taf.serial

taf.test("Communicate with GPS Device", {"hardware", "gps"}, function()
    -- Find a specific device by its USB product string
    local devices = serial.list_devices()
    local gps_path
    for _, dev in ipairs(devices) do
        if dev.product and dev.product:find("GPS") then
            gps_path = dev.path
            break
        end
    end

    if not gps_path then
        taf.log_critical("GPS device not found!")
    end

    taf.log_info("Found GPS device at:", gps_path)
    local port = serial.get_port(gps_path)

    -- Ensure the port is closed at the end of the test
    taf.defer(function()
        port:close()
        taf.print("GPS port closed.")
    end)

    -- Open and configure the port
    port:open("rw")
    port:set_baudrate(9600)
    port:set_bits(8)
    port:set_parity("none")
    port:set_stopbits(1)
    
    taf.print("Port configured. Waiting for NMEA sentence...")

    -- Read until we get a GPGGA sentence, with a 5-second timeout
    local sentence = port:read_until("$GPGGA", 5000)

    if sentence:find("$GPGGA") then
        taf.log_info("Received GPGGA sentence:", sentence)
    else
        taf.log_error("Did not receive a GPGGA sentence in time.")
    end
end)

---

### Where it stands

Works on macOS and Linux (Windows native support is in progress, WSL should just work).
Docs live in the repo (docs/ + annotated examples).
Apache 2.0 licence.

---

### Road-map / looking for feedback

Parallel test execution (isolated Lua states + fork() / threads).
Docker/Podman helper to spin up containers as ephemeral environments.
Better WebDriver convenience layer: CSS/XPath shorthands, wait-until helpers, drag-and-drop, screenshots diffing.
Pre-built binaries via GitHub Actions so you can `curl | sh` it in CI.
TAF self test (Test TAF with TAF)

If any of this sounds useful, grab it: <https://github.com/jayadamsmorgan/taf> (name collision with aviation “TAF” accepted 😅). Star, issue, PR, critique – all welcome!

Cheers!

lua classes and complex numbers!

I wrote a small (60 loc) lua system that implements classes, and wrote a complex number class using it (and 800 lines of tests), and a fractal renderer (in roblox) with it

Connecting via Websocket to a server.

So as a quick fun project, I wanna develop a mod for the game "Balatro" coded in lua with LÖVE2D, using the SteamModded framework and the lovely injector. Recently I've been hitting a wall. I need to connect as a client to a server via websocket and be able to recieve and send json messages. I have looked on the internet for solutions but I wanna ask here. (Btw I do know the syntax as its easy to adopt from python, and i do understand lua code).

- I've looked at lua-webhooks, but for a client I needed the ev module (for events it seems?) and for the love i cant find out how to get that module.
- I've looked at another Balatro Mod that adds multiplayer and uses sockets, but that's all i could find out. I am unsure what it does repo.
- And I've found lua-http, but i couldnt find any big documentation on it.

Help appreciated!

LuaDroid: why is some of the noscript not displaying in the output?

BACKGROUND ON THE OP:
I am quite new to lua. I've only been learning for a few days and I can grasp the basic principles of it. I have prior knowledge about coding and basic ideas as I'd learned most of python a few years back (I have forgotten nesrly all of what I had learned though).

I've been using roblox studio to learn when I'm at home but when travelling, I use LuaDroid. It is quite useful and, while I obviously can't practice stuff that need a 3d world and things that roblox studio has and LuaDroid doesn't, I can still practice if statements, maths, for and while loops, etc.

So anyways this is the issue: the noscript after line 61 (apart from comments because they don't appear anyway) just won't show up in the output. I've made a few functions after line 61 and then called them for use later but they aren't displayed in the output. I just don't understand why so someone please help me!

I'll paste my coding and what shows up in the output below. Also please tell me if I need to include more information about this because I don't know how much information you'd need to be able to tell me what I've done wrong.




Here's all of my coding (don't mind some of my word choices... hehe):




print("what the john is this")
-- thats the only thing i know how to do
-- how do i access lessons help

end

local sigma = 0

Lua on microcontrollers. Surprised how far it’s come

Been mostly using lue for small noscripting stuff over the years, config files, quick automation etc. Always loved how clean it feels but never thought of it as a serious option for embedded devices.

Recently tried out a setup where you run lua code directly on an esp32 and it honestly blew me away. Like full noscripting, GPIO access, MQTT, TLS, even OTA updates and all of it handled from a browser based IDE. Didn’t expect that level of capability from such a tiny chip running Lua.

Curious if anyone else here is experimenting with Lua on constrained devices? I know NodeMCU is a thing, but this felt a bit more full featured.

Putting my WebSocket into a Thread

## THIS IS A REPOST
Hi. I have been using https://github.com/flaribbit/love2d-lua-websocket/releases to create a simple websocket system for my Balatro mod. It all worked until some time ago. Only me on my laptop specifically and on the pc of a friend the game lags with 0fps. I have been able to pinpoint it to the löve2d socket library, specifically connect. I've learned that it's reccommended to put the socket in a Thread to avoid blocking operations stopping the game thread. I have never used threads in löve nor lua ever so I wanted to ask what would be the best way to rewrite my socket into using a thread without needing much of a refactor, since my code in this version is still spaghetti 🍝

How to list Windows pipes in Lua? (mpv)

Hi all,
I am trying to wait until a detached child process has created a named pipe, so that I don't send a command before the named pipe has been created (therefore making the command not take effect).

For this reason I am trying to list all the named pipes.

If I do dir -n \\.\pipe in the terminal (PowerShell), I get a list of all named pipes.

However, if I do the following in Lua (in an mpv noscript), I get nothing out:

for dir in io.popen([[dir -n "\\.\pipe"]]):lines() do print(dir) end

What's the best way to achieve what I'm trying to do?

Thanks
